Describe the bug

When updating an attribute for example with a client, the version in the client table should be updated as well.

This way it ensures that no-one else updated any other attribute in the meantime.

Version

17.0.0-SNAPSHOT

Expected behavior

Version number should be updated when an attribute changes

Actual behavior

No change in the version number, as the relation is owned by the "Many" side.

How to Reproduce?

• Enable JPA Map storage for clients
• Edit a client attribute like "Backchannel Logout Session Required"
• look at the client table and see if the version changes

Anything else?
